connection with planters.

The object of this invention is to increase the efliciency and utilityof attachments of,

improve and this character, and to generall to provide a simplify theconstruction, an

thoroughly practical, contrivance which will.

perform, its functions accurately and positively,

Other and further objects will manifest themselves in the followingspecification, and in the drawings, in which latter like characters ofreference denote similar parts throughout the several views.

applied to the shoe of a Referring to the drawings, Figure 1, .is a viewin perspective showing the invention lanter, the shoe being but partlyshown. ig. 2, is a like view, the scrapers and disks however, beingomitted to more closely disclosethe construction ofthe frame-work, Fig.3, is a top'pla n View of 1, and Fig. 4:, 1s a detail view in erspectivedepicting the frame element w ich sup orts the scrapers and the disks indetac ed position. 1

In the drawings 1, desi nates the shoe of a planter which has the we 1known and'usual association with the seed tube 2, to which two elementsthe invention is applied.

. As more clearly illustrated in Fig. 4, the frame element 3, embodies abody portion 4, which for the sake of lightness is formed U- sha e incross section. At itslower end this on' which the disks 7, are mountedand carb0 y is formed with enlargements or bosses 5, which serve thepurpose of roviding rigid and substantial supports for t e stub axle 6,

ried. These disk axles have an angular disposition with respect to thebodysides so asto cause the dis s to form an acute angle with oneanother at the front or forward partof the shoe 1, for the obviouspurpose, asis well known in the art, to cause the furrow to be widenedin gradual manneru At the top'portion: of the body, side thereof, isprovided an outstanding horion each zontal lug, or projection 8, eachofwhich is provided with an elongated slot 9. These ugs or projectionsprovide seats for the I scrapers 10,

U-shape so as to a low the free end thereof to roject downwardly andenga e the outer si e of the disks at points inwarc of the eripherythereof. The opposite ends of t ese scrapers are turned outwardly atapproximate right angles as at 11, and engage the lugs or projections 8,being held thereon by nuts and bolts the latter each comprising a bed ofstrip metal of general 12, which latter extend through slots 9, and

are movable along the lengths thereof, which enabl'esthe free ends ofthe scrapers to be adjusted towards or away from the disks as desired orfound necessar The front face of bocfjf 4, isformed with a I forwardlyprojecting lug 13, formed with a head 14, which projects thereof.

1 5,1'5, desi nates a pair of vertical bars which at their ower ends aresuitably formed to engage the shoe 1, these bars being arbeyond eachside ranged on opposite sides of' the shoe and on opposite sides of thelug 13, each being en-' gaged b the front face. of the body 4, and thehea 14, by means of which the bars'are held rigidly against transversemovement. Bolts and nuts 16 and 17, serve to effectually clamp thesebars to the shoe 1, the headed in and body 4. BodyA, is also assisted inbeing stationarily related to the shoe and 'seed tube by means of apairof horizontal bars 18, and 19, which latter at their rear ends areshaped to embrace and snugly engage on opposite sides of seed tube 2, to

which they are firmly clamped in unison by bolt and nut 20. The frontends of bars 18 and 19, are shown seated on lugs 8 and .111

dividually secured to the corresponding sides of body 4, by bolts, asillustrated. Thus body 4, is r gidly supported or suspended,

and may, as is manifest be raised or lowered, at will, with respect toshoe 1, by mere unloosening of bolts'17 and 20.

The disks are de icted as formed with hollow' hubs 21, which receive thefree ends of stubaxles 6, the disks being held in relative position ontheir axles by virtue of being engaged by the scrapers 10.

y use of washers between the inner faces of the disks and the bearingpoints 22,"0f axles 6, the disks may be adjusted inwardly or outwardlywith respect to the shoe as desired.

The invention, as is manifest, got only provides an attachment which isri idly reated to the shoe, but further one which is serviceable andwhich embodies but few parts. Moreover, the extreme simplicity invclvedin its operative securement to the shoe, adds to its eneraldesirability,- Having thus fully described our invention, what we claimas new and desire to secure by Letters Patent is 1. In combination withthe shoe of a lanter a furrow o )ener embod in a frame I 0 elementcarrying disks, a headed lug projecting outwardly from the front face ofsaid element, ahorizontal lug on each side of said element, a scrapersecured to each lug, and

means to secure said element with respect to said shoe.

' 2. In combination with the seed tube and shoe of a a frame e ementcarrying disks, a headed element rejecting outwardly from the front faceof sald frame element, a pair of bars on opposite sides of said headedelement disposed between the front face of the frame element and thehead of the headed element so as to be held against outward movement bysaid head, means to clamp said bars to I said headed element and to theslice, and bars secured to the up or end of the frame element and to thesee tiibe of the shoe and clam ed to each.

, 3. n combination with the shoe and seed tube of a planter, a frameelement of U- I sha e in cross section, an outwardly projecting ug oneach side of said frame clement ad- I jacent the top thereof, diskscarried by the frame element, a scraper secured to each lug,

horizontal bars on opposite sides of said l frame element seating on thetop faces of said lugs, means to secure said bars to said frame elementand to the seed tube, a headedlug rojecting outwardly from the frontface of said frame element, a, pair of vertical. bars engaged betweenthe head of said lug and the front face of said frame element, and meansfor clamping said vertical lanter, a furrow opener embodying bars tosaid headed lug and to the shoe.

In testimony whereof we have signed our names to the specification inthe presence of two subscribing witnesses.
